Packaging system and blanks therefor

ABSTRACT

A package (94) comprising at least one first inner carrier (92) and a second outer carrier (90), the or each of the at least one first inner carrier (92) having a first tubular structure, the second outer carrier (90) also having a tubular structure, and the second outer carrier being disposed, at least in part, on the outside of the first inner carrier such that the axes of the tubular structures are substantially perpendicular.

FIELD OF THE INVENTION

The present invention relates to consumer packages comprising at least two wraparound style carriers and more particularly, but not exclusively, to a package comprising at least two substantially perpendicularly oriented wraparound style carriers such that the completed package comprises four end walls.

BACKGROUND OF THE INVENTION

In the field of packaging it is often required to provide consumers with a package comprising multiple primary product containers. Such multi-packs are desirable for shipping and distribution and for display of promotional information. Wraparound style carriers are known in which a blank is wrapped around a group of articles to secure the group together for ease of transportation, shelf replenishment and sale. Such blanks may be wrapped over the top of the group of articles, or such blanks may comprise apertures through which the necks of articles pass as the blank is wrapped around the group. Two side panels extend alongside two sides of the group of articles and a composite bottom wall is typically formed by locking two bottom panels together, in a tensioned manner, such that the wrapped blank tightly holds the articles in their group.

Wraparound carriers are typically formed with only two sides and this results in a reduction in costs of the carrier because of the reduced amount of material required. A disadvantage of this, however, is that two ends of the group of articles are exposed, are less protected, and less “bill-board” area is available for the printing and display of branding, advertising and other sales driving indicia.

A further advantage of wraparound carriers is that assembly of the carriers can be automated at high speed, because there is no requirement for significant manipulation of the blank or of the group of articles. Disadvantageously however, the simple wraparound structure relies upon the tight fit of the blank about the article group in order to retain structural integrity. This means that as soon as a consumer removes an article from the group, the “tight fit” and hence the structural integrity of the package is compromised. As a consequence the useful life of the wraparound carrier is typically limited to the point at which an article is removed, at which time the remaining articles of the group become more difficult to handle.

For cost and environmental considerations, it is still preferable if such carrier and packages are formed from as little material as possible and cause as little wastage in the materials from which they are formed as possible. Another consideration is the strength of the packaging and its suitability for holding and transporting large weights of articles. A further consideration is the contribution the carrier makes to the appearance and overall value of the packaged goods, particularly in relation to its brand enhancement capability and its ability to stand out on a store shelf and attract consumers to purchase the grouped articles.

The present invention seeks to provide an improvement in the field of packaging, more specifically wraparound packaging, by providing a package comprising at least two wraparound carriers, which wraparound carriers are oriented substantially perpendicularly to one another such that the completed package comprises four side walls. The at least two wraparound carriers may comprise co-operative features; for example, the carriers may be lockable to one another.

The blanks can be alternatively configured to form a carrier for packaging other types, number and size of article and/or for packaging articles in a different arrangement or configuration.

Referring now to FIG. 1, there is shown a plan view from above of a first inner blank 10 according to a first embodiment of the disclosure. The first inner blank is optionally a wraparound style blank 10. The first inner blank 10 is suitable for being paired with a second outer blank, such as but not limited to, the second outer blank 11 shown in FIG. 2.

The first inner blank 10 comprises a series of main panels which form the main walls of a first inner carrier 92 once the first inner blank 10 is assembled. The series of main panels include: a first bottom panel 12, a first bevel panel 14, a first side panel 16, a second bevel panel 18, a top panel 20, a third bevel panel 22, a second side panel 24, a fourth bevel panel 26 and a second bottom panel 28. The main panels 12, 14, 16, 18, 20, 22, 24, 26, 28 are hinged one to the next in series along fold lines 30, 32, 34, 36, 38, 80, 82 and 84.

Additionally, first and second end panels 50, 52 are coupled to the top panel 20 by fold lines 60, 64 respectively. To automatically articulate the first and second end panels 50, 52 into position when the blank 10 is assembled, four gusset panels 54 a, 54 b, 54 c, 54 d and four web panels 56 a, 56 b, 56 c, 56 d are hinged between the first and second end panels 50, 52 and the first and second side panels 16, 24 respectively. As can be seen, each gusset panel 54 a, 54 b, 54 c, 54 d is hinged by a fold line 64 a, 64 b, 64 c, 64 d to the first or second side panel 16, 24; and each gusset panel 54 a, 54 b, 54 c, 54 d is hinged by a fold line 58 a, 58 b, 58 c, 58 d to an adjacent web panel 56 a, 56 b, 56 c, 56 d. Each web panel 56 a, 56 b, 56 c, 56 d is, in turn, hinged to an adjacent first or second end panel 50, 52 along a fold line 57 a, 57 b, 57 c, 57 d. As described further below, as the first and second side panels 16, 24 are folded relative to the top panel 20, the four gusset panels 54 a, 54 b, 54 c, 54 d and four web panels 56 a, 56 b, 56 c, 56 d are folded and moved and cause the first and second end panels 50, 52 to also fold relative to the top panel 20.

To facilitate the mechanical interlocking of the first and second bottom panels 12, 28, the first and second bottom panels 12, 28 are provided with complementary locking means. Optionally, the illustrated complementary locking arrangement comprises two female tabs F1, F2 in the first bottom panel 12; and two male locking tabs M1, M2 in the second bottom panel 28.

Optional alignment apertures A1, A3 are provided in the second bottom panel 28. The alignment apertures A1, A3 facilitate the automated location of the second bottom panel 28 relative to the first bottom panel 12.

Optional article heel engaging features H1, H2, H3, H4 are provided for engaging and securely locating the heel of an article. Each heel engaging feature H1, H2, H3, H4 is formed in part in a bevel panel 14, 26, in part in a bottom panel 12, 28 and in part in a side panel 16, 24. The presence of the heel engaging features H1, H2, H3, H4 is entirely optional; and when provided, the configuration of the heel engaging features H1, H2, H3, H4 may take many and various forms. As such, the configuration of each heel engaging feature H1, H2, H3, H4 illustrated in FIG. 1 is merely an example and is in no way limiting. Optionally, each of the four heel engaging features H1, H2, H3, H4 shown has the same configuration and therefore only one will be described.

Heel engaging feature H1 comprises a bottom aperture 40, a pair of inwardly foldable retention tabs 46 a, 44 a, and an upper aperture 42. The pair of inwardly foldable retention tabs 46 a, 44 a is each foldably connected to the first bottom panel 12, first bevel panel 14 and first side panel 16 by means of arcuate fold lines 46, 44. Optionally each inwardly foldable retention tab 46 a, 44 a may comprise a score or cut therethrough to facilitate its inward bending when displaced during assembly of the blank 10 about an article group.

The second and third bevel panels 18, 22 optionally comprise a weakened arrangement 68 a, 72 a, 70 a adjacent to each endmost aperture 2 a, 2 b, 2 c, 2 d. Since the weakened arrangements 68 a, 72 a, 70 a are optionally similar, only one is described. Aperture 2 c is defined in part by a cut line that is co-linear with fold line 38 and which terminates at short, arcuate fold lines 4 c and 4 e respectively (see FIG. 1). Adjacent to the aperture 2 c a slit 72 a extends from an edge of the aperture 2 c down to fold line 80. A first weakened line 68 a extends at an angle away from the junction of the cut line and the short, arcuate fold line 4 c, towards but not reaching the fold line 80. A second weakened line 70 a extends at an angle away from the junction of the cut line and the short, arcuate fold line 4 e, towards but not reaching the fold line 80. The weakened arrangement 68 a, 72 a, 70 a defines a tab 66 a which can be displaced out of the plane of the third bevel panel 22 (see FIG. 4) once the first inner carrier 92 is assembled. The four weakened arrangements may assist in removal of an article B from the carrier 92 when assembled.

The top panel 20 comprises an article receiving arrangement that is defined by a series of displaceable flaps 20 a, 20 b, 20 c, 20 d, shaped to form four apertures 2 a, 2 b, 2 c, 2 d in blank form. The displaceable flaps 20 c, 20 d are hinged to adjacent first and second end panels 50, 52 respectively by fold lines 60, 64. Displaceable flap 20 d is hinged via short, arcuate fold lines 4 a, 4 c to the top panel 20. Displaceable flap 20 c is hinged via short, arcuate fold lines 4 b, 4 d to the top panel 20. Displaceable flaps 20 a, 20 b are hinged to one another along fold line 62; and are each hinged to the top panel 20 along short, arcuate fold lines 4 h, 4 g, 4 e, 4 f. Displaceable flaps 20 d, 20 a share a common cut line 66; and displaceable flaps 20 b, 20 c share a common cut line 68.

To facilitate the co-operation and locking together of the inner wraparound carrier 92 and the outer wraparound carrier 90, a mechanical interlocking mechanism is provided. The mechanical interlocking mechanism optionally comprises one or more locking apertures provided on the inner wraparound carrier 92 and one or more corresponding and co-operating locking tabs provided in the outer wraparound carrier 90. In the present embodiment, the blank 10 is optionally provided with a locking aperture A2; and a pair of recesses R1, R2. The locking aperture A2 is formed in the second bottom panel 28. The aperture A2 is sized and positioned for receiving a locking tab from the outer wraparound carrier 92.

The first recess R1 is inset from an edge of the first bottom panel 12; and the second recess R2 is inset from an edge of the second bottom panel 28. The recesses R1, R2 are sized, positioned and arranged such that once a composite bottom wall structure 12/28 is formed, the recesses R1, R2 overlap to a sufficient extent such that a further aperture or gap R1/R2 is provided in the composite bottom wall structure 12/28, which further aperture or gap R1/R2 is sized and positioned for receiving a locking tab from the outer wraparound carrier 92.

Turning to the construction of the first inner wraparound carrier 92 as illustrated in FIGS. 3, 4 and 5, the first inner carrier 92 may be formed by a series of sequential folding operations in a straight line machine so that the first inner carrier 92 is not required to be rotated or inverted to complete its construction. The folding process is not limited to that described below and may be altered according to particular manufacturing requirements.

To prepare the blank 10, each pair of inwardly foldable retention tabs 46 a, 44 a of the heel engaging features H1, H2, H3, H4 is folded inwardly towards the adjacent first or fourth bevel panels 14, 26.

The six articles B are arranged in a 3×2 group having two opposite ends (of three articles) and two opposite sides (of two articles). Then the top panel 20 is aligned with the articles B such that a top closure C, for example a crown closure, of each of the four articles B on a side of the article group is beneath one of the four apertures 2 a, 2 b, 2 c, 2 d. The blank 10 is then lowered and placed over the tops of all of the articles B such that a top C of the four articles B on a side of the article group B passes through one of the apertures 2 a, 2 b, 2 c, 2 d. This action causes the displaceable flaps 20 a, 20 b, 20 c, 20 d to fold upwardly, out of the plane of the top panel 20 such that two rows of three articles each sit within an elongate aperture thereby formed in the top panel 20.

The second and third bevel panels 18, 22 are folded about fold lines 36 and 38 respectively and the first and second side panels 16, 24 are then folded about fold lines 34 and 80 until the first and second side panels 16, 24 are each disposed alongside a side of the article group. As the first and second side panels 16, 24 are folded, the four gusset panels 54 a, 54 b, 54 c, 54 d and the four web panels 56 a, 56 b, 56 c, 56 d automatically articulate the first and second end panels 50, 52, about fold lines 60, 64 respectively until the first and second end panels 50, 52 are each disposed alongside an end of the article group.

The first bottom panel 12 and first bevel panel 14 are then folded about fold lines 30 and 32 until the first and second article heel engaging features H1, H2 are located about the heels of two articles B along the side of the group and the first bottom panel 12 is disposed beneath part of the article group.

Similarly, the second bottom panel 28 and fourth bevel panel 26 are folded about fold lines 80 and 82 until the third and fourth heel engaging features H3, H4 are located about the heels of two other side articles within the group. Then, second bottom panel 28 is disposed beneath part of the article group until it partially overlaps the first bottom panel 12. The first and third apertures A1, A3 (generally triangular shaped apertures) within the second bottom panel 28 may be used by automating machinery to ensure proper positioning and relative alignment of the first and second bottom panels 12, 28.

Optionally, to form a bottom wall structure, the first and second bottom panels 12, 28 are mechanically locked together by punching the first and second male tabs M1, M2 against the first and second female tabs F1, F2. This displaces the first and second female tabs F1, F2 and creates apertures, through which the first and second male tabs M1, M2 are punched through. The shoulders of the first and second male tabs M1, M2 prevent the locking male tabs M1, M2 from returning back through the apertures formed when the first and second female tabs F1, F2 are displaced. In this way, the first and second bottom panels 12, 28 are mechanically locked together. The first and second bottom panels 12, 28 are mechanically locked together such that the group of articles B are tightly packed and held together in the carrier 92. The ends of the article group (not shown) are covered only partially by the first and second end panels 50, 52 but are otherwise exposed.

The inner wraparound carrier 92 formed from the blank 10 has a first notional tubular axis that is defined as extending between the open ends of the carrier 92, in other words between first end panel 50 and second end panel 52. The first notional tubular axis is parallel to the bottom wall structure 12/28.

The locking aperture A2 and further aperture or gap R1/R2 formed from the overlaying recesses R1, R2 are ready for receiving a locking tab from the outer wraparound carrier 90.

The outer wraparound carrier 90 is compatible with the inner wraparound carrier 92 and may take many and various forms. For example, the blank 11 shown in FIG. 2 may be assembled into one such suitable outer wraparound carrier 90, it being recognised that the illustrative example provided does not limit to a particular or specific combination of inner wraparound carrier and outer wraparound carrier.

In FIG. 2 it can be seen that the blank 11 comprises a series of main panels which form the main walls of a second outer carrier 92 once the second outer carrier blank 11 is assembled. The series of main panels include: a first bottom panel 25, a first side panel 23, a first bevel panel 21, a top panel 19, a second bevel panel 17, a second side panel 15, and a second bottom panel 13. The main panels 25, 23, 21, 19, 17, 15 and 13 are hinged one to the next in series along fold lines 37, 35, 33, 31, 29 and 27.

To facilitate the mechanical interlocking of the first and second bottom panels 25, 13 of the outer wraparound carrier 90 formed from the blank 11, the first and second bottom panels 25, 13 are provided with complementary locking means. Optionally, the illustrated complementary locking arrangement comprises two female tabs F3, F4 in the second bottom panel 13; and two male locking tabs M3, M4 in the first bottom panel 25.

Optional alignment apertures A4, A5, A6, A7, A8, A9 are provided in the second bottom panel 13 and first bottom panel 25. The alignment apertures A4, A5, A6, A7, A8, A9 facilitate the automated location of the second bottom panel 13 relative to the first bottom panel 25.

Optional article top engaging features T1, T2, are provided for engaging and securely locating the top or crown or closure ‘C’ of an article B. Each article top engaging feature T1, T2 is formed in part in a bevel panel 21, 17 and in part in the top panel 19. The presence of the article top engaging features T1, T2 is entirely optional; and when provided, the configuration of the top engaging feature T1, T2 may take many and various forms. As such, the configuration of each article top engaging feature T1, T2 illustrated in FIG. 2 is merely an example and is in no way limiting. Optionally, each of the article top engaging features T1, T2 shown has the same configuration and therefore only one will be described.

Article top engaging feature T1 comprises an upper aperture 43 defined in part by a cut edge 45 of the top panel 19; a pair of outwardly displaceable, foldable retention tabs 47 a, 47 b separated by a common cut line 51 and each hinged to the first bevel panel 21 via fold lines 39 a, 39 b.

The blank 11 also comprises a carrying feature which is structured and arranged to enable a user to comfortably and securely grip the outer carrier 90 for carrying and lifting the package 94 (see FIG. 3) formed from the combination of the assembled blank 10, a group of articles B and the assembled blank 11. The carrying feature is symmetrical and therefore only one side will be described. A recessed region is defined in the top panel 19 and comprises a first tab 53 a hinged to a centre tab 55 a along angled fold line 61 a and a second tab 59 a hinged on the other side of the centre tab 55 a by angled fold line 63 a. The centre tab 55 a is hinged to the top panel 19 along fold line 65 a; and the first and second tabs 53 a, 59 a are separated from the top panel 19 by means of an optional cut line. In use the center tab 55 a can be displaced out of the plane of the top panel 19 as it hinges downwardly about fold line 65 a. The first and second tabs 53 a, 59 a are also displaced out of the plane of the top panel 19 and fold downwardly relative to the top panel 19 and slightly inwardly towards the center tab 55 a. To carry the second outer wraparound carrier 90 (once assembled) a user can grip the top panel 19 using a pinching action, pressing their thumb against the center tab 55 a of one side of the carrying feature and by pressing any one or more or all of their index, middle and ring fingers against the other center tab 55 b and adjacent first and second tabs 53 b, 59 b.

Turning to the construction of the second outer wraparound carrier 90 as illustrated in FIGS. 3, 4 and 5, the second outer wraparound carrier 90 may be formed by a series of sequential folding operations in a straight line machine so that the second outer wraparound carrier 90 is not required to be rotated or inverted to complete its construction. The folding process is not limited to that described below and may be altered according to particular manufacturing requirements.

The top panel 19 is aligned with the articles within the first inner carrier 92 such that a top closure C, for example a crown closure, of each one of the articles B is beneath the top panel 19. The blank 11 is then lowered and placed onto the tops of the articles B such that a top C of each article B contacts an underside of the top panel 19. The first and second bevel panels 21, 17 are folded about fold lines 33 and 31 respectively and the first and second side panels 23, 15 are then folded about fold lines 35 and 29 until the first and second side panels 23, 15 are each disposed alongside an end of the article group. As the first and second bevel panels 21, 17 are folded, the article top engaging features T1, T2 are tightly fitted around the tops of the centre-most articles of the group. In this way, the second outer carrier 90 comprises an article engaging structure T1, T2 and a top portion C of at least one of the articles B of the group in the first inner carrier 92 is received, at least in part, within the top article engaging structure T1, T2 of the second outer tubular structure 90.

The second bottom panel 13 is folded about fold line 27 until the second bottom panel 13 is disposed beneath part of the bottom wall structure 12/28 of the inner wraparound carrier 92.

Similarly the first bottom panel 25 is then folded about fold line 37 until the first bottom panel 25 is disposed beneath part of the second bottom panel 13 and part of the bottom wall structure 12/28 of the inner wraparound carrier 92. The alignment apertures A4, A5, A6, A7, A8, A9 (generally triangular shaped apertures) within the second bottom panel 13 and first bottom panel 25 may be used by automating machinery to ensure proper positioning and relative alignment of the first and second bottom panels 25, 13.

Optionally, to form a bottom wall structure of the outer wraparound carrier 90, the first and second bottom panels 25, 13 are mechanically locked together by punching the first and second male tabs M3, M4 against the first and second female tabs F3, F4. This displaces the first and second female tabs F3, F4 and creates apertures, through which the first and second male tabs M3, M4 are punched.

Advantageously, the male tabs M3, M4 of the mechanical locking mechanism of the second outer wraparound carrier 90 are aligned with the locking aperture A2 and gap R1/R2 of the first inner carrier 92. When the male tabs M3, M4 are punched through the first and second female tabs F3, F4 of the second bottom panel 13 of the outer wraparound carrier 90, the male tabs M3, M4 are also punched through one of the locking aperture A2 or gap R1/R2 of the inner carrier 92.

The shoulders of the first and second male tabs M3, M4 are pushed past the outer bottom wall structure and through and into the interior region of the first inner wraparound carrier 92. This prevents the locking male tabs M3, M4 from accidentally returning back through locking aperture A2; gap R1/R2 of the first inner carrier 92; and the apertures formed when the first and second female tabs F1, F2 are displaced. In this way, the first and second bottom panels 25, 13 are mechanically locked together to form a composite bottom wall structure of the second outer carrier 90. The inner wraparound carrier 92 and the group of six articles B are tightly packed and further held together in the outer wraparound carrier 90. The ends of the article group (not shown) are now more fully covered by the first and second side and bevel panels 23/21, 17/15 of the second outer wraparound carrier 90. Furthermore, the composite bottom wall structure of the second outer carrier 90 is mechanically locked to the composite bottom wall structure of the first inner carrier 92.

The outer wraparound carrier 90 formed from the blank 11 has a second notional tubular axis that is defined as extending between the open ends of the carrier 90. The second notional tubular axis is parallel to the bottom wall structure 25/13.

As such a package 94 is formed which comprises a first inner carrier 92 and a second outer carrier 90 with the second outer carrier 90 being disposed, at least in part, on the outside of the first inner carrier 92. The tubular axis of the first inner carrier 92 is perpendicular to the second tubular axis of the second outer carrier 90.

The two sets of carrying feature 53 a/55 a/59 a and 53 b/55 b/59 b, together provide a carrying handle structure and individually provide a spacer between adjacent centremost articles B3, B4 of the article group.

The carrying handle structure comprises, as described, one or more foldable tabs and optionally, in this arrangement, each set of carrying features comprises three tabs: the first tab 53 a, 53 b, the center tab 55 a, 55 b, and the second tab 59 a, 59 b. In FIG. 5, the carrying handle structure is in use, and only part of the carrying handle structure is therefore visible.

In use, the foldable tabs 53 a/55 a/59 a, 53 b/55 b/59 b have all been folded out of the plane of the top panel 19; and the first and second tabs 53 a, 53 b, and 59 a, 59 b have also been folded inwardly, out of the plane of the center tab 55 a, 55 b and toward the center tab 55 a, 55 b. The center tab 55 a, 55 b, along with the adjacent and angled first and second tabs 53 a, 53 b, 59 a, 59 b, forms a generally “U”-shaped structure that is sized and arranged to fit between the necks N of the two center most articles i.e. between bottles B3 and B4 (see FIG. 5).

The two folded carrying handle features 53 a/55 a/59 a, 53 b/55 b/59 b are disposed on either side and partially between the centermost articles B3, B4. They can be gripped in a pinching type hold, optionally between a user's thumb, which might contact the center tab 55 a, and a user's index and middle fingers, which might contact the other center tab 55 b.

In this way the carrying handle features 53 a/55 a/59 a, 53 b/55 b/59 b can each provide, when folded downwardly into the interior of the package 94, a spacer that is positioned between two adjacent articles B3, B4 and a carrying handle for the entire package 94.

The package 94 (see FIG. 3) encloses at least a lower portion of the group of articles due to the provision of the side walls 23/21, 15/17, of the second outer carrier 90 about each of the sides of the group of articles and the provision of the side panels 16, 24 of the first inner carrier 92 about each of the ends of the group of articles. To remove an article, the shoulder S of a side-most bottle B may be pulled against the weakened arrangement 68 a, 70 a, 72 a and pulled past the displaceable flaps 20 a, 20 b, 20 c, 20 d until a sufficiently sized gap ‘O’ is created such that the bottle B can be lifted out of the inner and outer wraparound carriers 90, 92 of the package 94 (see FIG. 4).

Once articles have been removed (see FIG. 5) the package 94 may comprise empty openings ‘O’ where a bottle B was positioned, yet the package 94 still retains much of its structural integrity. This is somewhat different to typical wraparound carriers where, upon removal of one or more articles, the wraparound carrier typically collapses. In the present arrangement the package 94 retains structural integrity, even after the removal of two or more or all bottles B5, B6 as shown. This is in part due to a keel structure or bracing structure formed by the combination of displaceable tabs 20 a, 20 b, fold line 62 and the arcuate short fold lines 4 h, 4 g, 4 e, 4 f at either end thereof that couple the displaceable tabs 20 a, 20 b to the second and third bevel panels 18, 22 respectively.

This keel structure may provide a brace across the first inner carrier 92 which helps to preserve the structural rigidity of the first inner carrier 92 even after the articles have been removed. This keel structure is optionally centrally disposed and as shown in FIG. 3 has a substantially inverted “V”-shaped cross-section. The keel structure may brace or provide support between the first and second side panels 16, 24.

Referring now to FIGS. 6, 7 and 8, there is shown a second embodiment of the present invention wherein an alternative inner blank 110 is shown which can be combined with a second outer blank in order to construct a different package 194. For example, but without limitation, the first inner blank 110 may be combined with the second outer blank 11 of FIG. 2, as illustrated in FIGS. 7 and 8. In the second illustrated embodiment, like numerals have, where possible, been used to denote like parts, albeit with the addition of the prefix “100” to indicate that these features belong to the second embodiment. The second embodiment shares many common features with the first embodiment and therefore only the differences from the embodiment illustrated in FIGS. 1 to 5 will be described in any greater detail.

The first inner blank 110 comprises a series of main panels which form the main walls of a first inner carrier 192 once the first inner blank 110 is assembled. The series of main panels include: a first bottom panel 112, a first bevel panel 114, a first side panel 116, a top panel 120, a second side panel 124, a fourth bevel panel 126 and a second bottom panel 128. The main panels 112, 114, 116, 120, 124, 126, 128 are hinged one to the next in series along fold lines 130, 132, 136, 180, 182 and 184.

Again first and second end panels 150, 152 are coupled to the top panel 120 by fold lines 160, 164, and in this arrangement the first and second end panels 150, 152 are coupled to the first and second side panels 116, 124 via four gusset panels 154 a, 154 b, 154 c, 154 d and four web panels 156 a, 156 b, 156 c, 156 d, which are hinged by fold lines 164 a, 164 b, 164 c, 164 d; 158 a, 158 b, 158 c, 158 d; and 157 a, 157 b, 157 c, 157 d respectively. The four gusset panels 154 a, 154 b, 154 c, 154 d and four web panels 156 a, 156 b, 156 c, 156 d automatically articulate the first and second end panels 150, 152 into a set up position when the blank 110 is assembled.

To facilitate the mechanical interlocking of the first and second bottom panels 112, 128, the first and second bottom panels 112, 128 are provided with complementary locking means. Optionally, the illustrated complementary locking arrangement comprises two female tabs F11, F12 in the first bottom panel 112; and two male locking tabs M11, M12 in the second bottom panel 128.

Optional alignment apertures A11, A13 are provided in the second bottom panel 128 for facilitating the automated location of the second bottom panel 128 relative to the first bottom panel 112.

Optional article heel engaging features H11, H12, H13, H14 are also provided and have a similar structure to the heel engaging features H1, H2, H3, H4 already described.

The top panel 120 comprises a different article receiving arrangement compared to the blank 10 of FIG. 1. The article receiving arrangement is defined by a series of transversely arranged displaceable flaps 120, 120 a, 120 b, 120 c, 120 d, 120 that run between the end panels 150, 152 of the blank 110. The six displaceable flaps 120, 120 a, 120 b, 120 c, 120 d, 120 are shaped to form six apertures 102 a, 102 b, 102 c, 102 d, 102 e, 102 f in bank form.

A first part of the top panel 120 that is hinged to the first side panel 116 along fold line 136 forms a first displaceable flap having a shaped cut edge defined by cut line 166. The cut line 166 also defines a shaped cut edge of a second displaceable flap 120 a. The second displaceable flap 120 a is hinged to the top panel 120 by means of a transversely extending fold line 162 a and short arcuate fold lines 104 a, 104 b, 104 c, 104 d, which extend from the transversely extending fold line 162 a to the adjacent first and/or second end panel 150, 152 respectively.

A third displaceable flap 120 b is also hinged to the top panel 120 by means of the transversely extending fold line 162 a and short arcuate fold lines 104 a, 104 b, 104 c, 104 d, which extend from the transversely extending fold line 162 a to the adjacent first and/or second end panel 150, 152 respectively. The third displaceable flap 120 b has a shaped cut edge defined by cut line 168. The cut line 168 also defines a shaped cut edge of a fourth displaceable flap 120 c.

The fourth displaceable flap 120 c is also hinged to the top panel 120 by means of a further transversely extending fold line 162 b and short arcuate fold lines 104 e, 104 f, 104 g, 104 h, which extend from the transversely extending fold line 162 b to the adjacent first and/or second end panel 150, 152 respectively. The fourth displaceable flap 120 d has a shaped cut edge defined by cut line 169. The cut line 169 also defines a shaped cut edge of a fifth displaceable flap 120, which is part of the top panel 120 and that is hinged to the second side panel 124 along fold line 180.

To facilitate the co-operation and locking together of the inner wraparound carrier 192 formed from the blank 110 (see FIG. 7) with an outer wraparound carrier 90, a mechanical interlocking mechanism is provided. The mechanical interlocking mechanism optionally comprises one or more locking apertures provided on the inner wraparound carrier 192 and the co-operating locking tabs M3, M4 provided in the outer wraparound carrier 90. In the present embodiment, the blank 110 is again optionally provided with a locking aperture A12; and a pair of similarly shaped recesses R11, R12. The locking aperture A12 is formed in the second bottom panel 128 and has a substantially octagonal shape. The aperture A12 is sized and positioned for receiving a locking tab M3, M4 from the outer wraparound carrier 90.

As in the first embodiment of FIG. 1 a first recess R11 that is inset from an edge of the first bottom panel 112; and a second recess R12 that is inset from an edge of the second bottom panel 128 are sized, positioned and arranged such that once the bottom wall structure 112/128 is formed, the recesses R11, R12 overlap to a sufficient extent that a further aperture or gap R11/R12 is provided in the bottom wall structure 112/128, which further aperture or gap R11/R12 is sized and positioned for receiving a locking tab M3, M4 from the outer wraparound carrier 90.

The construction of the first inner wraparound carrier 192 (see FIG. 7) is similar to that already described in relation to the first inner wraparound carrier 92, albeit, when the top panel 120 is lowered and placed over the tops of the articles B1, B2, B3, B4, B5, B6, a top C of each article B1, B2, B3, B4, B5, B6 passes through one of the apertures 102 a, 102 c, 102 e, 102 b, 102 d, 102 f. This action causes the displaceable flaps 120, 120 a, 120 b, 120 c, 120 d, 120 to each fold upwardly about fold lines 136, 162 a, 162 b and 180 respectively such that three transverse rows, each comprising two articles B1/B4, B2/B5, B3/B6, are disposed within a transverse aperture 102 a/102 b, 102 c/102 d, 102 e/103 f, thereby formed.

The first and second side panels 116, 124 are then folded about fold lines 136 and 180 until they are each disposed alongside a side of the article group. Again, this action automatically articulates the first and second end panels 150, 152, about fold lines 160, 164 respectively until the first and second end panels 150, 152 are each disposed alongside part of an end of the article group (see FIG. 7).

The first bottom panel 112 and first bevel panel 114 are folded as described before, with the first and second article heel engaging features H11, H12 being located about the heels of two articles B4, B1 along a first side B1/B4 of the group of articles and with the first bottom panel 112 being disposed beneath part of the article group.

Similarly, the second bottom panel 128 and fourth bevel panel 126 are folded as described before with the third and fourth heel engaging features H13, H14 being located about the heels of two articles B6, B3 along a second side B3/B6 of the group of articles and with the second bottom panel 128 being disposed beneath part of the article group and in partial overlapping relationship with the first bottom panel 112. The mechanical interlocking mechanism M11, M12, F11, F12 can then be operated to secure the first and second bottom panels 112, 128 together as previously described.

In this way, the first and second bottom panels 112, 128 are mechanically locked together such that the group of articles B1, B2, B3, B4, B5, B6 is tightly packed and held together within the first carrier 192. The ends B1/62/63, B4/B5/B6 of the article group (see FIG. 7) are covered only partially by the first and second end panels 150, 152 but are otherwise exposed.

A first keel structure or bracing structure is formed by the combination of displaceable tabs 120 a, 120 b, fold line 162 a and the arcuate short fold lines 104 a, 104 c, 104 b, 104 d at either end thereof that couple the displaceable tabs 120 a, 120 b to the top panel 120. The first keel structure forms a brace between a first row of articles B1/B4 and a second row of articles B2/B5.

A second keel structure or bracing structure is formed by the combination of displaceable tabs 120 c, 120 d, fold line 162 b and the arcuate short fold lines 104 e, 104 g, 104 f, 104 h at either end thereof that couple the displaceable tabs 120 c, 120 d to the top panel 120. The second keel structure forms a brace between the second row of articles B2/B5 and a third row of articles B3/B6.

The keel structure may provide a structural brace across the first inner carrier 92 which helps to preserve the structural rigidity of the first inner carrier 92 even after the articles have been removed. Optionally the keel structure has a substantially inverted “V” shaped cross-section. The keel structure may brace or provide support between the first and second side panels 15, 23 of a second outer carrier 90.

The locking aperture A12 and further aperture or gap R11/R12 formed from the overlaying recesses R11, R12 are ready for receiving a locking tab M3, M4 from the outer wraparound carrier 90.

The outer wraparound carrier 90 compatible with the inner wrap around carrier 92 may take many and various forms. For example, the blank 11 shown in FIG. 2 may be assembled into one such suitable outer wraparound carrier 90, it being recognised that the illustrative example provided does not limit to a particular or specific combination of inner wraparound carrier and outer wraparound carrier.

The second outer wraparound carrier 90 may be assembled about the inner carrier 92 and article group B1-B6 shown in FIG. 7, in the same manner as described above, with the top panel 19 being placed onto the tops of the articles B1-B6 and such that the first and second bevel panels 21, 17 and the first and second side panels 23, 15 are folded until the article top engaging features T1, T2 are tightly fitted around the tops of the centre-most articles B2, B5 of the group.

The second bottom panel 13 is folded about fold line 27 until the second bottom panel 13 is disposed beneath part of the bottom wall structure 112/128 of the inner wraparound carrier 192.

Similarly the first bottom panel 25 is then folded about fold line 37 until the first bottom panel 25 is disposed beneath part of the second bottom panel 13 and part of the bottom wall structure 112/128 of the inner wraparound carrier 192.

Again, to form a bottom wall structure of the outer wraparound carrier 90, the first and second bottom panels 25, 13 are mechanically locked together by punching the first and second male tabs M3, M4 against the first and second female tabs F1, F2. This displaces the first and second female tabs F1, F2 and creates apertures, through which the first and second male tabs M3, M4 are punched.

Advantageously, the male tabs M3, M4 of the mechanical locking mechanism of the second outer wraparound carrier 90 are aligned with the locking aperture A12 and gap R11/R12 of the first inner carrier 192. When the male tabs M3, M4 are punched through the first and second female tabs F1, F2 of the second bottom panel 13 of the outer wraparound carrier 90, the male tabs M3, M4 are also punched through one of the locking aperture A12 and gap R11/R12 of the inner carrier 192.

The first and second bottom panels 25, 13 are mechanically locked together to form a composite bottom wall structure of the second outer carrier 90. The inner wraparound carrier 192 and the group of six articles B1-B6 are tightly packed and further held together in the outer wraparound carrier 90. The ends of the article group B1/62/63, B4/B5/B6 are now more fully covered by the first and second side and bevel panels 23/21, 17/15 of the second outer wraparound carrier 90. Furthermore, the composite bottom wall structure 25/13 of the second outer carrier 90 is mechanically locked to the composite bottom wall structure 112/128 of the first inner carrier 192.

As before, the outer wraparound carrier 90 formed from the blank 11 has a second notional tubular axis that is defined as extending between the open ends of the carrier 90. The second notional tubular axis is parallel to the bottom wall structure 112/128.

As such a package 194 is formed which comprises a first inner carrier 192 and a second outer carrier 90 with the second outer carrier 90 being disposed, at least in part, on the outside of the first inner carrier 192. The tubular axis of the first inner carrier 192 is perpendicular to the second tubular axis of the second outer carrier 90.

As shown in FIG. 8, the two sets of carrying feature 53 a/55 a/59 a and 53 b/55 b/59 b together provide a carrying handle structure and individually provide a spacer between adjacent centremost articles B2, B5 of the article group.

Once articles have been removed (not shown) the package 194 may again comprise empty openings ‘0’ where a bottle B1-B6 was positioned, yet the package 194 still retains much of its structural integrity. This is in part due to the transverse keel structure or bracing structure formed by the combination of displaceable tabs 120 a, 120 b,120 c, 120 d fold lines 162 a, 162 b and the arcuate short fold lines 104 a, 104 b, 104 c, 104 d, 104 e, 104 f, 104 g, 104 h at either end thereof that couple the displaceable tabs 120 a, 120 b, 120 c, 120 d to the end panels 150, 152 respectively.

This keel structure may provide a brace across the first inner carrier 192 which helps to preserve the structural rigidity of the first inner carrier 192 even after the articles B1-B6 have been removed. The keel structures are optionally centrally disposed and as shown in FIG. 6 provide two transverse structures with inverted “V” shaped cross-sections. The keel structures may brace or provide support between the first and second side panels 116, 124.

Referring now to FIGS. 9, 10, 11 and 12, there is shown another embodiment of the present invention wherein an alternative inner blank 210 is shown which can be combined with the second outer blank 11 of FIG. 2 in order to construct a different package 294. In the third illustrated embodiment like numerals have, where possible, been used to denote like parts, albeit with the addition of the prefix “200” to indicate that these features belong to the third embodiment. The third embodiment shares many common features with the first embodiment and therefore only the differences from the embodiment illustrated in FIGS. 1 to 5 will be described in any greater detail.

Referring now to FIG. 9, there is shown a plan view from above of a first inner blank 210 according to the third embodiment of the disclosure. The first inner blank 210 is also optionally a wraparound style blank 210 and is suitable for being paired with a second outer blank, such as but not limited to, the second outer blank 11 shown in FIG. 2.

The first inner blank 210 again comprises a series of main panels which form the main walls of a first inner carrier 292 shown in FIGS. 10, 11 and 12. The series of main panels includes: a first bottom panel 212, a first bevel panel 214, a first side panel 216, a top panel 220, a second side panel 224, a fourth bevel panel 226 and a second bottom panel 228. The main panels 212, 214, 216, 220, 224, 226, 228 are hinged one to the next in series along fold lines 230, 232, 236, 280, 282 and 284.

The first inner blank 210 optionally does not comprise second and third bevel panels either side of the top panel 220, and also does not comprise any end panels. Similarly to the first inner blank 10 of FIG. 1, the first inner blank 210 does comprise a mechanical interlocking means for the first and second bottom panels 212, 228. Optionally, the illustrated complementary locking arrangement comprises two female tabs F21, F22 in the first bottom panel 212; and two male locking tabs M21, M22 in the second bottom panel 228.

The first inner blank 210 also optionally comprises alignment apertures A21, A23; optional article heel engaging features H21, H22, H23, H24 which operate in the same manner as heel engaging features H1, H2, H3, H4 of blank 10; and a pair of recesses R21, R22 which are provided, as before, to facilitate the co-operation and locking together of the inner wraparound carrier 292 and the outer wraparound carrier 90.

The top panel 220, as shown in FIG. 9, also comprises an article receiving arrangement that is also optionally defined by a series of four longitudinally extending, displaceable flaps 220 a, 220 b, 220 c, 220 d. In this arrangement however, the four displaceable flaps 220 a, 220 b, 220 c, 220 d are shaped to form six apertures 202 a, 202 b, 202 c, 202 d, 202 e, 202 f in blank form. A common cut line 266 separates displaceable flaps 220 a, 220 b; and similarly, a common cut line 268 separates displaceable flaps 220 c, 220 d. The common cut lines 266, 268 are interrupted by the apertures 202 a, 202 b, 202 c, 202 d, 202 e, 202 f respectively. In other embodiments, the optional apertures 202 a, 202 b, 202 c, 202 d, 202 e, 202 f may be omitted, beneficially however, they provide a clear indication for alignment of the top panel 220 with the article group.

Additionally, the outermost displaceable flaps 220 a and 220 d are hinged to the top panel 220 by means of curved or arcuate fold lines 204 a, 204 c, 204 b and 204 d respectively. The curved fold lines 204 a, 204 c, 204 b and 204 d are longer in length than the short arcuate fold lines 4 a, 4 b, 4 c, 4 d of the first embodiment. This may be in order to ensure that the outermost displaceable flaps 220 a, 220 d are attached to the top panels 220 by a sufficiently strong connection because there are no end panels in this arrangement.

Similarly the centre-most displaceable flaps 220 b, 220 c, as well as being hinged to one another along a common fold line 262, are hinged to the top panel 220 via long arcuate fold lines 204 e, 204 f, 204 g, 204 h.

In this embodiment, however, the displaceable flaps 220 a, 220 b, 220 c, 220 d are folded downwardly out of the plane of the top panel 220. Optionally this may be achieved by pushing the bottoms of the bottles B1, B2, B3, B4, B5, B6 onto the top panel 220 which causes the flaps 220 a, 220 b, 220 c, 220 d to fold to create an opening for the two rows of three bottles B1/62/63, B4/65/66.

To complete the construction of the first inner wraparound carrier 292, the first and second side panels 216, 224 are then disposed alongside one of the sides B1/B2, B3/B6 of the article group. The first bottom panel 212 and first bevel panel 214 are then folded until the first and second article heel engaging features H21, H22 are located about the heels of the two articles B3, B6 on one side of the group and then the second bottom panel 228 and fourth bevel panel 226 are folded until the third and fourth heel engaging features H23, H24 are located about the heels of the two articles B1, B2 on the other side of the article group. Then, to form a bottom wall structure, the first and second bottom panels 212, 228 are mechanically locked together by punching the first and second male tabs M21, M22 against the first and second female tabs F21, F22.

Alternatively the displaceable flaps 220 a, 220 b, 220 c, 220 d may be folded downwardly out of the plane of the top panel 220 in a pre-assembly step, after which the open top panel 220 is located onto the tops of the articles B1, B2, B3, B4, B5, B6, and by relative movement of the blank 210 and articles, the blank 210 is then pulled down the necks of the articles B1, B2, B3, B4, B5, B6 and the construction of the blank 210 about the articles group completed as described before.

However formed, the inner wraparound carrier 292 formed from the blank 210 has a first notional tubular axis that is defined as extending between the open ends of the carrier 292, in other words along a line running through the middle of the centremost articles B2, B5. The first notional tubular axis is parallel to the bottom wall structure 212/228.

The locking aperture A22 and further aperture or gap R21/R22 formed from the overlaying recesses R21, R22 are again ready for receiving a locking tab from an outer wraparound carrier 90.

The outer wraparound carrier compatible with the inner wraparound carrier 292 may take many and various forms. For example, the blank 11 shown in FIG. 2 may be assembled into one such suitable outer wraparound carrier 90, it being recognised that the illustrative example provided does not limit to a particular or specific combination of inner wraparound carrier and outer wraparound carrier.

The outer wraparound carrier 90 and its assembly need not be described again and in FIGS. 10 and 12 the package 294 can be seen. Once articles have been removed (see FIG. 11 for a partially emptied package 294) the package 294 may comprise two empty openings ‘O’ where bottles B1-B6 were positioned, yet the package 294 still retains much of its structural integrity. The package 294 again retains structural integrity, even after the removal of two B4, B1 bottles shown, or more bottles. This is in part due to a keel structure or bracing structure formed by the combination of displaceable tabs 220 b, 220 c, fold line 262 and the arcuate fold lines 204 h, 204 g, 204 e, 204 f at either end thereof.

This keel structure again may provide a brace across the first inner carrier 292 which helps to preserve the structural rigidity of the first inner carrier 292 even after the articles have been removed. This keel structure is optionally centrally disposed and as shown in FIG. 11 has a substantially inverted “V” shaped cross-section. The keel structure may brace or provide support between the first and second side panels 216, 224.

Referring now to FIGS. 13 to 16, there is shown a further embodiment of the present invention wherein an inner blank 310 may be combined with a second outer blank 311 in order to construct an alternative package 394. In the fourth illustrated embodiment like numerals have, where possible, been used to denote like parts, albeit with the addition of the prefix “300” to indicate that these features belong to the fourth embodiment. This embodiment shares many common features with the previous embodiments and therefore only the differences from the embodiments illustrated in FIGS. 1 to 12 will be described in any greater detail.

A first inner blank 310 is shown in FIG. 14 comprising a series of main panels which form the main walls of a first inner carrier 392 once the first inner blank 310 is assembled.

FIG. 16 illustrates a portion of the composite bottom panel 312, 328; the articles B1, B2, B3, B4 have been removed for illustrative purposes.

The male tab M32 has passed through the first bottom panel 312, in doing the female tab F32 was displaced out of the plane of the first bottom panel 312. The female tab F32 bears against the male tab M32. The inherent resilience of the material from which the blank 310 is formed biases the female tab F32 against the male tab M32, so as to hold in a folded position. The male tab M31 and female tab F31 are similarly arranged albeit not visible in FIG. 16.

The male tab M33 of the second outer carrier 390 has passed through the first bottom panel 325 of the second outer carrier 390. In doing the female tab F33 was displaced out of the plane of the first bottom panel 325. The female tab F33 bears against the male tab M33. The inherent resilience of the material from which the blank 311 is formed biases the female tab F33 against the male tab M33, so as to hold in a folded position. The male and female tabs M33, F33 have also passed through the composite bottom panel 312/328 of the first inner carrier 392. The male and female tabs M33, F33 are received in the aperture in the composite bottom panel 312/328 formed by the recesses R31, R32. The male tab M33 may be substantially arrowhead shaped and comprise engaging shoulders, the engaging shoulders may be in locking engagement with the composite bottom panel 312/328 of the first inner carrier 392 so as to lock the composite bottom panel 312/328 of the first inner carrier 392 to the composite bottom panel 325/313 of the second outer carrier 390.

FIG. 16 also illustrates the relationship between the alignment apertures A31, A32, A33, A35 in the first inner carrier 392 and the alignment apertures A34, A36, A37, A38 in the second outer carrier 390.

The alignment apertures A31, A32, A33, A35 in the first inner carrier 392 allow a machine tool to pass through both the composite bottom panel 325/313 of the second outer carrier 390 and the composite bottom panel 312/328 of the first inner carrier 392. The alignment apertures A31, A32, A33, A35 in the first inner carrier 392 are shaped and/or dimensioned such that the machine tool when inserted has freedom to move the first and second bottom panels 325, 313 of the second outer carrier 390 with respect to each other.

The first and second web panels of the first side panel 423 may be bent about the shoulder of the respective one of the articles B4, B3 such that the first and second web panels are non-coplanar with the remainder of the first side panel 423.

Referring now to FIGS. 20, 21, 22 and 23, there are shown further embodiments of the present invention, including a first inner wraparound blank 510 for use with a second outer wraparound blank 511, which form a package 594 according to a sixth embodiment. In the sixth illustrated embodiment like numerals have, where possible, been used to denote like parts, albeit with the addition of the prefix “500” to indicate that these features belong to the sixth embodiment. The embodiment shown in FIGS. 20 to 23 shares many common features with the earlier described embodiments and therefore only the differences from the embodiment illustrated in FIGS. 1 to 19 will be described in any greater detail.

Referring now to FIG. 20, the first inner blank 510 again comprises a series of main panels which form the main walls of a first inner carrier 590 shown in FIG. 22. The series of main panels include: a first bottom panel 512, a first bevel panel 514, a first side panel 516, a second bevel panel 518, a top panel 520, a third bevel panel 522, a second side panel 524, a fourth bevel panel 526 and a second bottom panel 528. The main panels 512, 514, 516, 518, 520, 522, 524, 526, 528 are hinged one to the next in series along fold lines 530, 532, 534, 536, 538, 580, 582 and 584.

The first inner blank 510 optionally does not comprise any end panels, or displaceable flaps or keel structure. Similarly to the first inner blank 10 of FIG. 1, the first inner blank 510 does comprise a mechanical interlocking means for the first and second bottom panels 512, 528. Optionally, the illustrated complementary locking arrangement comprises two female tabs F51, F52 in the second bottom panel 528; and two male locking tabs M51, M52 in the first bottom panel 512.

The first inner blank 510 also optionally comprises alignment apertures A51, A53; and optional article heel engaging features H51, H52, H53, H54 which operate in the same manner as heel engaging features H1, H2, H3, H4 of blank 10. In this arrangement, the pair of recesses R1, R2 is replaced with a locking aperture A55 which is formed in the first bottom panel 512 and is provided to facilitate the co-operation and locking together of the inner wraparound carrier 590 and the outer wraparound carrier 592.

The second locking aperture A55 optionally has a generally hexagonal shaped edge and may comprise two opposed fold lines 509 a, 509 b and two opposed tabs 507 a, 507 b. The two opposed tabs 507 a, 507 b may be hinged about the fold lines 509 a, 509 b. The two opposed tabs 507 a, 507 b may be displaced by one or more locking tabs M53, M54 of a second outer carrier 592. The presence of the two displaced opposed tabs 507 a, 507 b in the locking arrangement may enhance the security with which the first carrier 590 is interlocked with the second carrier 592.

In the second bottom panel 528 a further locking aperture A52 is provided, which will overlap or be aligned with the locking aperture A55 of the first bottom panel 512 and the locking tabs 507 a, 507 b may assist in locking the first and second bottom panels 512, 528 to one another.

The second and third bevel panels 518, 522 optionally comprise a weakened arrangement 570 a, 570 b, 570 c, 570 d adjacent to each endmost aperture 502 a, 502 b, 502 e, 502 f. Since the weakened arrangements 570 a, 570 b, 570 c, 570 d are optionally similar, only one is described. Aperture 502 e is defined in part by a circular cut line that lies adjacent to fold line 538. Adjacent to the aperture 502 e a slit 570 c extends at an angle in the third bevel panel 522. The weakened arrangements 570 a, 570 b, 570 c, 570 d can be broken to assist in removal of an article B from the carrier 590 when assembled.

The top panel 520, as shown in FIG. 20, also comprises an article receiving arrangement, but in contrast to the embodiment of FIGS. 1 to 5, the article receiving arrangement does not comprise displaceable flaps. In this arrangement six apertures 502 a, 502 b, 502 c, 502 d, 502 e, 502 f are provided in the top panel 520, each one for receiving a top and neck portion of an article B1, B2, B3, B4, B5, B6. The article receiving arrangement also optionally comprises a series of frangible lines 504 a, 504 b, 504 c, 504 d, 506 a, 506 b, 506 c, 506 d that emanate radially outward from an edge of an aperture 502 a, 502 b, 502 c, 502 d, 502 e, 502 f as shown in FIG. 20. The frangible lines 504 a, 504 b, 504 c, 504 d, 506 a, 506 b, 506 c, 506 d are sized, shaped, positioned and otherwise arranged to facilitate the withdrawal of an article by pulling it upwardly and causing a tear to propagate along one or more of the frangible lines 504 a, 504 b, 504 c, 504 d, 506 a, 506 b, 506 c, 506 d such that the aperture 502 a, 502 b, 502 c, 502 d, 502 e, 502 f associated with the article being removed is increased in size to allow the shoulder of that bottle to be lifted through the opening thereby created.

To preserve the integrity of the top panel 520, at least to some extent after one or more articles have been so removed, the article receiving arrangement may also comprise one or more terminations or edge cuts E1, E2, E3, E4, which terminations are optionally provided at the end of one, some or all of the frangible lines 504 a, 504 b, 504 c, 504 d, 506 a, 506 b, 506 c, 506 d in order to limit the extent to which a tear may propagate along the top panel 520.

The illustrated article receiving arrangement may differ in some embodiments to accommodate articles of different size, shape, number, and/or arrangement and/or the illustrated article receiving arrangement may differ in terms of the frangible lines and terminations provided which control the manner in which, and the ease with which, an article can be pulled free of the carrier 590.

The first inner wraparound carrier 590 of the present embodiment (see FIG. 22) is assembled by first placing the top panel 520 over the tops of a group of six articles arranged in a 3×2 group, such that a neck of one article from the group is received in each of the apertures 502 a, 502 b, 502 c, 502 d, 502 e, 502 f. Construction of the carrier 590 is completed as described in respect of earlier embodiments with the second and third bevel panels 518, 522 and the first and second side panels 516, 524 being disposed alongside one of the sides B1/B4, B3/B6 of the article group. The first bottom panel 512 and first bevel panel 514 are then folded until the first and second article heel engaging features H51, H52 are located about the heels of the two articles B3, B6 on one side of the group and then the second bottom panel 528 and fourth bevel panel 526 are folded until the third and fourth heel engaging features H53, H54 are located about the heels of the two articles B1, B4 on the other side of the article group. Then, to form a bottom wall structure, the first and second bottom panels 512, 528 are mechanically locked together by punching the first and second male tabs M51, M52 against the first and second female tabs F51, F52.

The locking apertures A54 and A55 overlap and together with locking aperture A52, the inner carrier bottom wall is ready for interlocking with the outer carrier 592 by locking tabs from the outer wraparound carrier 592 being inserted into the locking apertures A54/A55, A52.

The outer wraparound carrier 592 compatible with the inner wraparound carrier 590 may take many and various forms. For example, the blank 511 shown in FIG. 21 may be assembled into one such suitable outer wraparound carrier 592, it being recognised that the illustrative example provided does not limit to a particular or specific combination of inner wraparound carrier and outer wraparound carrier.

In FIG. 21 it can be seen that the blank 511 is similar to the blank 11 of FIG. 2, but instead has differently shaped first and second bevel panels 521, 517 which give the overall carton an asymmetric appearance. Each first and second bevel panel 521, 517 has a skewed shape defined by slanted side edges. In contrast to the blank 11 of FIG. 2, the blank 511 of FIG. 21 additionally comprises first and second inset panels 527 a, 527 b that are foldably connected to an edge of the first and second side panels 523, 515 respectively via fold lines 539 a, 539 b.

To allow the inset panels 527 a, 527 b to fold freely, the first and second bottom panels 525, 513 are disconnected from the inset panels 527 a, 527 b.

A further difference between the blank 511 of FIG. 21 and the blank 11 of FIG. 2 is in the provision of shaped “female” locking tabs F53, F54 which in this arrangement have a greater width than the rectangular female tabs of blank 11. The locking tabs F53, F54 have shoulders and a leading edge that is narrower in width than the width of the locking tabs across their shoulders.

Yet a further difference between the blank 511 and blank 11 is that the carrying handle features are formed within and are surrounded by part of the top panel 519 rather than being formed in a recessed region at an edge of the top panel 519. Fully surrounded by the remainder of the top panel, each carrying handle feature comprises a first tab 553 a hinged to a Y-shaped centre tab 555 a along a shaped fold line 561 a and a second tab 559 a hinged on the other side of the Y-shaped centre tab 555 a by a shaped fold line 563 a (see FIGS. 21 and 23).

As before, in use the center tab 555 a can be displaced out of the plane of the top panel 519 as it hinges downwardly about fold line 565 a. The first and second tabs 553 a, 559 a are also displaced out of the plane of the top panel 519 and fold downwardly relative to the top panel 519 and slightly inwardly toward the center tab 555 a. To carry the second outer wraparound carrier 592 (once assembled) a user can grip the top panel 519 using a pinching action, pressing their thumb against the center tab 555 a of one side of the carrying feature and by pressing any one or more or all of their index, middle and ring fingers against the other center tab 555 b and adjacent first and second tabs 553 b, 559 b.

Otherwise, the blank 511 comprises a similar series of main panels including: a first bottom panel 525, a first side panel 523, a first bevel panel 521, a top panel 519, a second bevel panel 517, a second side panel 515, and a second bottom panel 513.

Turning to the construction of the package 594 as illustrated in FIG. 22, the second outer wraparound carrier 592 is aligned with the articles within the first inner carrier 590, lowered and placed onto the tops of the articles B1-B6. The first and second bevel panels 521, 517 are folded about fold lines 533 and 531 respectively and the first and second side panels 523, 515 are then folded about fold lines 535 and 529 until the first and second side panels 523, 515 are each disposed alongside an end B1/B2/B3 of the article group. As the first and second bevel panels 521, 517 are folded, the article top engaging features T1, T2 are tightly fitted around the tops of the centre-most articles B2, B5 of the group. In this way, the second outer carrier 592 comprises an article engaging structure T1, T2 and a top portion C of at least one of the articles B2, B5 of the group in the first inner carrier 590 is received, at least in part, within the top article engaging structure T1, T2 of the second outer tubular structure 592.

The first and second inset panels 527 a, 527 b are folded inwardly towards the article group.

The second bottom panel 513 is disposed beneath part of the bottom wall structure 512/528 of the inner wraparound carrier 590. In this way, the locking tabs F53, F54 are aligned with and disposed beneath the locking apertures A52, A54/A55. The first bottom panel 525 is then folded about fold line 537 until the first bottom panel 525 is disposed beneath part of the second bottom panel 513 and part of the bottom wall structure 512/528 of the inner wraparound carrier 590. The male locking tabs M53, M54 are thereby disposed beneath both the female locking tabs F53, F54 and the locking apertures A52, A54/A55. The first and second male tabs M53, M54 are then pushed against the female tabs F53, F54 respectively. This displaces the female tabs F53, F54 into and through a respective one of the locking apertures and allows the male tabs to also be pushed into a respective one of the locking apertures F53, F54. In respect of the locking aperture A54/A55, this action also inwardly displaces the locking tabs 507 a, 507 b to form a secure interlocking of both the first and second bottom panels 512, 528 with one another and a secure interlocking of the first and second bottom panels 525, 513 of the outer carrier 592 with the first and second bottom panels 512/528 of the inner carrier 590.

Once the shoulders of both the first and second male tabs M53, M54 and of the first and second “female” tabs F53, F54 are pushed past the outer bottom wall structure 513/525 and through and into the interior region of the first inner wraparound carrier 590, return of the male and female tabs M53, M54, F53, F54 is prevented and the inner wraparound carrier 590 and outer wraparound carrier 592 are securely locked together, with the ends of the article group B1/62/63, B4/B5/B6 now being more fully (albeit still partially) covered by the first and second side and bevel panels 523/521, 517/515 of the second outer wraparound carrier 592.

The package 594 thus formed comprises a first inner carrier 590, a second outer carrier 592 and may be easily carried by the carrying features 553 a/555 a/559 a and 553 b/555 b/559 b, which as shown in FIG. 23 provide a carrying handle structure and individually provide a spacer between adjacent centremost articles B2, B5 of the article group.

Referring now to FIGS. 24, 25 and 26, there is shown a further embodiment of the present invention, including a first inner wraparound blank 610 for use with a second outer wraparound blank 611, which form a package 694 according to a seventh embodiment. In the seventh illustrated embodiment, like numerals have, where possible, been used to denote like parts, albeit with the addition of the prefix “600” to indicate that these features belong to the sixth embodiment. The inner wraparound blank 610 and the inner wraparound carrier 692 share many features in common with the embodiment shown in FIGS. 20 to 23; and the outer wraparound blank 611 and the outer wraparound carrier 690 share many features in common with the embodiment shown in FIGS. 2 and 21 and therefore only the differences from the earlier described embodiments will be described in any greater detail.

Referring now to FIG. 24, the first inner blank 610 is configured for holding four articles in a 2×2 arrangement and again comprises a series of main panels which form the main walls, which although does not comprise first and fourth bevel panels, does include: a first bottom panel 612, a first side panel 616, a second bevel panel 618, a top panel 620, a third bevel panel 622, a second side panel 624, and a second bottom panel 628.

Similarly to the first inner blank 510, the first inner blank 610 optionally does not comprise any end panels, or displaceable flaps or keel structure and further similarly to the first inner blank 510 of FIG. 20, the first inner blank 610 comprises a mechanical interlocking means for the first and second bottom panels 612, 628. Optionally, the illustrated complementary locking arrangement comprises two female tabs F61, F62 which are optionally generally rectangular in shape in the second bottom panel 628; and two male locking tabs M61, M62 in the first bottom panel 628.

In this arrangement, a second locking aperture A65 is again formed in the first bottom panel; and as with the blank 510 of FIG. 20, the second locking aperture A65 has a generally hexagonal shaped edge and may comprise two opposed fold lines 609 a, 609 b and two opposed, hinged tabs 607 a, 607 a. The two opposed tabs 607 a, 607 b may be hinged about the fold lines 609 a, 609 b. The two opposed tabs 607 a, 607 a may be displaced by a locking tab M63, M64 of a second outer carrier 690. The presence of the two displaced opposed tabs 607 a, 607 b in the locking arrangement may enhance the security with which the first carrier 692 is interlocked with the second carrier 690.

In the second bottom panel 628 a further locking aperture A64 is provided, which may overlap or be aligned with the locking aperture A65 of the first bottom panel 612 and the locking tabs 607 a, 607 b may assist in locking the first and second bottom panels 612, 628 to one another and/or to the outer carrier 692.

In this arrangement, the blank 610 optionally comprises additional apertures A32, A34 formed such that an edge of the aperture A32, A34 is coincident with the fold line 632, 684 between the first or second bottom panel 612, 628 and the adjacent first or second side panel 616, 624. The apertures A32, A34 may be used as alignment apertures for use during construction of the carrier 692, to ensure, for example, that the first and second bottom panels 612, 628 are properly aligned. The apertures A32, A34 may also receive interlocking features of the outer carrier 690.

The top panel 620, as shown in FIG. 24 comprises an article receiving arrangement, but in contrast to the embodiment of FIGS. 1 to 5, the article receiving arrangement does not comprise displaceable flaps. In this arrangement four apertures 602 a, 602 b, 602 c and 602 d are provided in the top panel 620, each one for receiving a top and neck portion of an article B1, B2, B3, B4. The article receiving arrangement also optionally comprises a series of four frangible lines 604 a, 604 b, 604 c, 604 d that each emanate radially outward from an edge of an aperture 602 a, 602 b, 602 c and 602 d as shown in FIG. 24. The frangible lines 604 a, 604 b, 604 c, 604 d, are sized, shaped, positioned and otherwise arranged to facilitate the withdrawal of an article by pulling it upwardly and causing a tear to propagate in the top panel 620 such that the aperture 602 a, 602 b, 602 c, 602 d associated with the article being removed is increased in size to allow the shoulder of that bottle to be lifted through the opening thereby created.

As before, the second and third bevel panels 618, 622 optionally comprise a weakened arrangement 668 a, 668 b, 670 a, 670 b adjacent to each of the four article receiving apertures 602 a, 602 b, 602 c, 602 d that are provided in the top panel 620. Since the weakened arrangements 668 a, 668 b, 670 a, 670 b are optionally similar, only one is described. Adjacent to the aperture 602 a the frangible line 604 a extends at an angle toward the first bevel panel 618; and toward a slit 668 b formed at a co-operative angle in the first bevel panel 618. The slit 668 b and frangible line 604 a can be broken and used to tear the top panel 620 and the first bevel panel 618 to assist in removal of an article B from the carrier 692 when assembled.

The first inner wraparound carrier 692 of the present embodiment (see FIG. 22) is assembled by first placing the top panel 690 over the tops of a group of four articles arranged in a 2×2 group, such that a neck of one article from the group is received in each of the apertures 602 a, 602 b, 602 c, 602 d. Construction of the carrier 692 is completed as described in respect of earlier embodiments with the second and third bevel panels 618, 622 and the first and second side panels 616, 624 being disposed alongside one of the sides B1/B2, B3/B4 of the article group. The first bottom panel 612 is then folded until the first and second article heel engaging features H61, H62 are located about the heels of the two articles B1, B2 on one side of the group and then the second bottom panel 628 is folded until the third and fourth heel engaging features H63, H64 are located about the heels of the two articles B3, B4 on the other side of the article group. Then, to form a bottom wall structure, the first and second bottom panels 612, 628 are mechanically locked together by punching or pressing the first and second male tabs M61, M62 against the first and second female tabs F61, F62.

The locking apertures A64 and A65 may overlap and prepare the inner carrier bottom wall for interlocking with the outer carrier 690 using a locking tab (M63 or M64) from the outer wraparound carrier 690.

The outer wraparound carrier 690 compatible with the inner wraparound carrier 692 may take many and various forms. In this arrangement, two inner carriers 692 a, 692 b are held by a single outer carrier 690, such that the overall package 694 contains 8 articles B1, B2, B3, B4, B1′, B2′, B3′, B4′ packaged into two separate carriers 692 a, 692 b, each comprising a 2×2 group of four articles. An example, of a carrier 690 suitable for combination with two inner carriers 692 a, 692 b is shown in FIG. 26. The carrier 690 is formed from a blank 611 as shown in FIG. 25. It will be recognised that the illustrative example provided does not limit to a particular or specific combination of inner wraparound carrier and outer wraparound carrier.

In FIG. 25 it can be seen that the blank 611 is similar to the blank 11 of FIG. 2, albeit, with larger sized panels to accommodate a greater number of articles B1, B2, B3, B4, B1′, B2′, B3′, B4′. Additionally, the top panel 619 is formed similarly to the top panel 520 of the blank shown in FIG. 21 wherein the carrying handle features are formed within and are surrounded by part of the top panel 619 rather than being formed in a recessed region at an edge of the top panel 619. Fully surrounded by the remainder of the top panel, each carrying handle feature again comprises a first tab hinged to a Y-shaped centre tab 655 a along a shaped fold line and a second tab hinged on the other side of the Y-shaped centre tab 655 a by a shaped fold line (see FIGS. 25 and 26).

As before, in use the center tab 655 a can be displaced out of the plane of the top panel 619 as it hinges downwardly. The first and second tabs are also displaced out of the plane of the top panel 619 and fold downwardly relative to the top panel 619 and slightly inwardly toward the center tab 655 a. To carry the second outer wraparound carrier 690 (once assembled) a user can grip the top panel 619 using a pinching action, pressing their thumb against the center tab 655 a of one side of the carrying feature and by pressing any one or more or all of their index, middle and ring fingers against the other center tab 655 b and adjacent first and second tabs.

Otherwise, the blank 611 comprises a similar series of main panels to the blank 11 of FIG. 2, including: a first bottom panel 625, a first side panel 623, a first bevel panel 621, the top panel 619, a second bevel panel 617, a second side panel 615, and a second bottom panel 613.

To interlock the outer carrier 690 formed from the blank 611 to the two inner carriers 692 a, 692 b, the first and second bottom panels 625, 613 are provided with shaped and wide locking tabs M63, M64, F63, F64 that co-operate as described above. In addition, the first bottom panels comprise one or more optional male tabs M65, M66 which co-operate with one or more corresponding female tabs F65, F66. This locking mechanism is provided to interlock the first and second bottom panels 625, 613 of the outer carrier 690 together and increases the security with which the bottom structure of the package 694 is held together. As can be seen the additional bottom locking features M65, M66, F65, F66 that interlock the first bottom panel 625 of the outer carrier 690 to the second bottom panel 613 of the outer carrier 690 to one another, are optionally provided in a central region of the blank 611. This may offer increased strength in the region where the two separate inner carriers 692 a, 692 b meet.

An optional series of alignment apertures A61, A62, A63, A54; A55, A66, A67, A68 are provided in the first and second bottom panels 625, 613, again for aiding the correct alignment of the first and second bottom panels 625, 613 with one another for interlocking the outer carrier 690 together and with the bottom walls 612/628, 612′/628′ of the inner carriers 692 a, 692 b.

The package 694 formed from two inner carriers 692 a, 692 b and the single outer carrier 690 is shown in FIG. 26. The package 694 is constructed by positioning two inner carriers 692 a, 692 b next to one another such that the second side panel 624 of a first one of the inner carriers 692 a is disposed next to and possibly in face contacting relationship with a first side panel 616′ of the second one of the inner carriers 692 b. This results in a 2×4 article array being formed.

The top panel 619 is then placed over the top of the eight bottle group B1, B2, B3, B4; B1′, B2′, B3′, B4′ and the first and second bevel panels 621, 617 folded down against the “open ends” of the inner carriers 692 a, 692 b. The first bevel panel 621 is disposed alongside a first end B2, B4, B2′, B4′ of the article group; and the second bevel panel 617 is disposed alongside a second end B1, B3, B1′, B3′ of the article group. The top engaging features T1 a, T1 b mate and locate with centremost articles B4, B2′; and the top engaging features T2 a, T2 b mate and locate with centremost articles B3, B1′.

After folding the first and second side panels firmly against the ends of the inner carriers 692 a, 692 b, the first and second bottom panels 625, 613 of the outer carrier are folded in turn, beneath the inner carriers 692 a, 692 b. The second bottom panel 613 is folded first and contacts the underside of the bottom wall structures of the inner carriers 692 a, 692 b such that the female locking tab F64 is disposed beneath locking aperture A64/A65 of the first inner carrier 692 a; and such that the female locking tab F63 is disposed beneath the locking aperture A64′/A65′ of the second inner carrier 692 b.

The first bottom panel 625 is then folded such that it contacts the underside of the bottom wall structures of the inner carriers 692 a, 692 b; and partially overlays the second bottom panel 613. In this way, the male locking tab M64 is aligned with and disposed beneath the female locking tab F64 and locking aperture A64/A65 of the first inner carrier 692 a; the male locking tab M63 is aligned with and disposed beneath the female locking tab F63 and locking aperture A64′, A65′ of the second inner carrier 692 b; and the additional male locking tabs M65, M66 are disposed beneath and aligned with the female tabs F66, F65 and apertures A32, A34.

To interlock the first and second bottom panels 625, 613 to one another; and to interlock the bottom wall 625/613 of the outer carrier 690 to the inner carrier 692 a: the male tab M64 is forced against the female tab F64, which pushes both the female tab F64 and the male tab M64 upwardly into the locking aperture A64/A65, which in turn pushes the tabs 607 a, 607 b up into the interior of the first inner carrier 692 a. The tabs 607 a, 607 b are disposed behind the female tab F64 and male tab M64 respectively and the shape and size of all tabs M64, F64, 607 a, 607 b are such that once punched upwardly into a locking position, return of the tabs to their starting position is very difficult indeed. In this way the outer carrier 690 is securely attached to the inner carrier 692 a. The male and female tabs M64, F64 may abut the edge of the aperture A65/A64 which may be shaped such that the shoulders of the male tab M64 overhang the edge of the aperture A65/A64 and sit on or just above the inner surface of the second bottom panel 628 of the first inner carrier 692 a.

This is shown in FIG. 27, which illustrates an internal view of part of the package with bottles removed. The first inner carrier 692 a is shown with its first side panel 616 to the right-hand side of the picture. The heel locking features H62, H61, with their foldable retention tabs 644 a folded, can be seen. Similarly, on the left-hand side of the picture, the second side panel 624 can be seen, with its heel locking features H63, H64 shown. Through the gaps created by the inward folding of the foldable retention tabs 644 a, the second inner carrier 692 b can be seen, in particular the first side panel 616′ thereof (on the very left-hand side of the picture). As can be seen the second bottom panel 628 of the inner carrier 692 a sits partially on top of the first bottom panel 612.

Similarly, to further interlock the first and second bottom panels 625, 613 to one another; and to interlock the bottom wall 625/613 of the outer carrier 690 to the inner carrier 692 b: the male tab M63 is forced against the female tab F63, which pushes both the female tab F63 and the male tab M63 upwardly into the locking aperture A64′/A65′, which in turn pushes the tabs 607 a′, 607 b′ up into the interior of the second inner carrier 692 b. The tabs 607 a′, 607 b′ are disposed behind the female tab F63 and male tab M63 and the shape and size of all tabs M63, F63, 607 a′, 607 b′ are such that once punched upwardly into a locking position, return of the tabs to their starting position is very difficult indeed. In this way the outer carrier 690 is securely attached to the second inner carrier 692 b. The male and female tabs M63, F63 may abut the edge of the aperture A65′/A64′ which may be shaped such that the shoulders of the male tab M63 overhang the edge of the aperture A65′/A64′ and sit on or just above the inner surface of the second bottom panel 628′ of the second inner carrier 692 b.

Furthermore, to interlock the first and second bottom panels 625, 613 to one another, male tabs M66, M65 are forced against female tabs F66, F65. The male and female tabs may be located in the apertures A34, A32′ respectively and may therefore provide additional interlocking of the inner and outer carriers 692 a, 692 b, 690.

To remove an article, the weakened arrangement 668 a, 668 b, 670 a, 670 b adjacent to each of the four article receiving apertures 602 a, 602 b, 602 c, 602 d can be broken; and even once one or more of the articles have been removed, the structural integrity of the package 694 remains.

Referring now to FIGS. 28 to 29, there is shown a further alternative embodiment of the present disclosure wherein an inner blank 710 may be combined with a second outer blank for example the blank 611 of FIG. 25 in order to construct a package 794. In the eighth illustrated embodiment, like numerals have, where possible, been used to denote like parts, albeit with the addition of the prefix “700” to indicate that these features belong to the eighth embodiment.

A fourth anchor panel 754 d is hingedly connected to a second side of the second side panel 724 by a fold line 753 d. The fourth anchor panel 754 d is hingedly connected, along an end thereof, to a fourth gusset panel 764 d by a fold line 758 d. The fourth gusset panel 764 d is hingedly connected to a fourth web panel 756 d by a fold line 763 d. The fourth web panel 756 d is hingedly connected to the second end panel 752 by a fold line 757 d.

To facilitate the mechanical interlocking of the first and second bottom panels 712, 728, the first and second bottom panels 712, 728 are provided with complementary locking means. Optionally, the illustrated complementary locking arrangement comprises two female tabs F71, F72 in the second bottom panel 728; and two male locking tabs M11, M12 in the first bottom panel 712.

Optional alignment aperture A71 is provided in the second bottom panel 728 for facilitating the automated location of the second bottom panel 728 relative to the first bottom panel 712. Optional alignment aperture A72 is provided in the first bottom panel 712 for facilitating the automated location of the second bottom panel 728 relative to the first bottom panel 712. Apertures A71 and A72 may also receive locking tabs of an outer carrier, such as outer carrier 690.

Optional article heel engaging features H71, H72, H73, H74 are also provided and have a similar structure to the heel engaging features H1, H2, H3, H4 already described, albeit with the addition of an aperture which separates in part the one of the pair of inwardly foldable retention tabs from the other of the pair of inwardly foldable retention tabs, and the inclusion of an additional fold line in each of the retention tabs, the additional fold line defining in part a substantially triangular web portion.

To facilitate the co-operation and locking together of the inner wraparound carrier 792 formed from the blank 710 (see FIG. 29) with an outer wraparound carrier, a mechanical interlocking mechanism is provided. The mechanical interlocking mechanism optionally comprises one or more apertures provided on the inner wraparound carrier 792 for co-operating with locking tabs provided in the outer wraparound carrier. In the present embodiment, the blank 710 is optionally provided with a first locking aperture A74 struck from the second bottom panel 728 and second locking aperture A75 struck from the first bottom panel 712. Optionally, the locking apertures A74, A75 have a substantially hexagonal shape.

The first side panel 716 comprises a first fold line 770 b which extends between an upper edge of the first side panel 716 and a first side edge; defined by fold line 753 a, of the first side panel 716 so as to be obliquely disposed.

The first side panel 716 comprises a second fold line 768 b which extends between an upper edge of the first side panel 716 and a second side edge; defined by fold line 753 b, of the first side panel 716 so as to be obliquely disposed.

The second side panel 724 comprises a third fold line 770 a which extends between an upper edge of the second side panel 724 and a first side edge; defined by fold line 753 c, of the second side panel 724 so as to be obliquely disposed.

The second side panel 724 comprises a second fold line 768 a which extends between an upper edge of the second side panel 724 and a second side edge; defined by fold line 753 d, of the second side panel 724 so as to be obliquely disposed.

Optionally the first, second, third and fourth fold lines 770 b, 768 b, 770 a, 768 a may be comprised of two or more linear sections divergently arranged with respect to each other.

The construction of the first inner wraparound carrier 792 is similar to that already described in relation to the first inner wraparound carrier 92, albeit, when the top panel 120 is lowered and placed over the tops of the articles B1, B2, B3, B4, a pair of articles B1, B2, B3, B4 passes through each of the apertures 720 a, 720 d. This causes the displaceable flaps 720 b, 720 c to each fold upwardly about fold line 762 b such that two transverse rows, each comprising two articles, are disposed within a transverse aperture thereby formed.

The first and second side panels 716, 724 are then folded about the group of articles until they are each disposed alongside a side of the article group. The anchor panels 754 a, 754 b, 754 c, 754 d are folded into face contacting relationship with the respective one of the first and second side panels 716, 724, as the first and second side panels 716, 724 are folded about the group of articles. Consequently, the first and second end panels 750, 752 are automatically erected about respective ends of the article group.

The first and second bottom panels 712, 728 are folded about the base of the article group. The heel engaging features H71, H72, H73, H74 each being located about a heel of an article along respective sides of the group of articles and with the first bottom panel 712 being disposed externally of, and in overlapping relationship with, the second bottom panel 728.

The mechanical interlocking mechanism M71, M72, F71, F72 can be operated to secure the first and second bottom panels 712, 728 together by displacing the male tabs M71, M72 inwardly to displace the female tabs F71, F72 and through the respective apertures in the second bottom panel 728 thereby formed.

In this way, the first and second bottom panels 712, 728 are mechanically locked together such that the group of articles B1, B2, B3, B4, are tightly packed and held together within the first carrier 792. The ends of the article group (see FIG. 29) are covered only partially by the first and second end panels 750, 752 but are otherwise exposed.

A keel structure or bracing structure is formed by the combination of displaceable tabs 720 b, 720 c, fold line 762 b and the fold lines 704 a, 704 c, 704 b, 704 d at either end thereof that couple the displaceable tabs 720 b, 720 c to the top panel 720. The keel structure forms a brace between a first row of articles B1/B4 and a second row of articles B2/B3.

The first, second, third and fourth fold lines 770 a, 768 a, 770 b, 768 b facilitate folding of upper end portions of the first and second side panels 716, 728 about the shoulder of an adjacently disposed the article B1, B2, B3, B4. In this way the first carrier forms a close fit with the group of articles. The first, second, third and fourth fold lines 770 a, 768 a, 770 b, 768 b may facilitate folding of said portions of the first and second side panels 716, 728 at least partially over the shoulder of an article B1, B2, B3, B4 thereby increasing the retention of the articles therein. The constructed inner carrier 792 is shown in FIG. 29.

To complete a package (not shown) one or more, for example two such inner carriers 792 may be housed within and locked and attached to an outer carrier, for example the outer carrier 690 of the previous embodiment.

It can be appreciated that various changes may be made within the scope of the present invention, for example, the size and shape of the panels and apertures may be adjusted to accommodate articles of differing size or shape.

It will be recognized that as used herein, directional references such as “top”, “bottom”, “front”, “back”, “end”, “side”, “inner”, “outer”, “upper” and “lower” do not necessarily limit the respective panels to such orientation, but may merely serve to distinguish these panels from one another.

As used herein, the terms “hinged connection” and “fold line” refer to all manner of lines that define hinge features of the blank, facilitate folding portions of the blank with respect to one another, or otherwise indicate optimal panel folding locations for the blank. A fold line is typically a scored line, an embossed line, or a debossed line. Any reference to hinged connection or fold line should not be construed as necessarily referring to a single fold line only; indeed it is envisaged that hinged connection can be formed from any one or more of the following, a short slit, a frangible line or a fold line without departing from the scope of the invention.

As used herein, the term “severance line” refers to all manner of lines that facilitate separating portions of the substrate from one another or that indicate optimal separation locations. Severance lines may be frangible or otherwise weakened lines, tear lines, cut lines, or slits.

It should be understood that hinged connection, severance lines and fold lines can each include elements that are formed in the substrate of the blank including perforations, a line of perforations, a line of short slits, a line of half-cuts, a single half-cut, a cut line, an interrupted cut line, slits, scores, any combination thereof, and the like. The elements can be dimensioned and arranged to provide the desired functionality. For example, a line of perforations can be dimensioned or designed with degrees of weakness to define a fold line and/or a severance line. The line of perforations can be designed to facilitate folding and resist breaking, to facilitate folding and facilitate breaking with more effort, or to facilitate breaking with little effort.
